Abstract

Kebutuhan kedelai semakin meningkat sedangkan produksi kedelai terus mengalami penurunan. Untuk itu diperlukan upaya untuk meningkatkan pertumbuhan kedelai, diantaranya dengan memanfaatkan G. gigas sebagai bahan organik. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian dosis G. gigas serta proporsi media tanam terhadap pertumbuhan tanaman kedelai. Penelitian ini dilaksanakan secara eksperimen menggunakan Rancangan Acak Kelompok (RAK) dengan dua faktor perlakuan, yaitu dosis bahan organik G. gigas dan proporsi media tanam (tanah : pasir). Faktor perlakuan dosis bahan organik G. gigas yaitu 0,1 gram; 3,6 gram; 7,8 gram dan 11,4 gram. Faktor proporsi media tanam antara tanah : pasir 1:1 (2,5 kg : 2,5 kg), 1:3 (1,25 kg : 3,75 kg), dan 3:1 (3,75 kg : 1,25 kg). Parameter yang diamati yakni pertumbuhan tanaman kedelai yang meliputi biomassa, tinggi, dan jumlah daun. Data dianalisis dengan menggunakan Anava 2 arah. Oleh karena itu jika dalam penelitian ini uji ANAVA menunjukan adanya perbedaan yang signifikan maka dilanjutkan dengan uji Duncan untuk membandingkan letak perbedaan antar perlakuan. Hasil penelitian menunjukan bahwa dosis bahan organik G. gigas dan proporsi media tanam berpengaruh terhadap pertumbuhan tanaman kedelai. Pertumbuhan tanaman kedelai dilihat dari tinggi tanaman diperoleh pada proporsi media tanam antara tanah dan pasir 3:1 dan dosis bahan organik G. gigas 7,8 gram. Dosis bahan organik G. gigas 7,8 gram dan proporsi media tanam antara tanah dan pasir 3:1  memberikan nilai ekonomis.   Kata kunci: Gracilaria gigas;  bahan organik; media tanam; pertumbuhan  kedelai.

Abstract

This study aims to determine the influence of audio-visual media assisted by the discovery learning model on the learning outcomes of grade V students of SD YWKA Palembang. This study uses a quantitative method of Quasi Experimental design experiment with pretest and posttest. The population of this study is all students of class V of SD YWKA Palembang which is 32 people. Based on the average posttest score obtained by the control class was 71.25 and the experimental class was 81.88. Hypothesis testing of the data of this study uses an independent sample t-test with hypothesis testing criteria, namely if the tcount > table. It was obtained with the values of tcount = 2.323 > ttable = 1.697 and sig. (2-tailed) = 0.027 < 0.05, then the calculation shows that Ha was accepted and Ho was rejected or the hypothesis states that there is an increase in the use of audio-visual media assisted by the discovery learning model on the learning outcomes of students in grade V of SD YWKA Palembang.
